Installation and maintenance The SD14 valve is assembled and tested as per the technical specification of this CATALOGUE . Before the final installation on your equipment, follow the below recommendations: -- the valve can be assembled in any position, in order to prevent body deformation and spool sticking mount the product on a flat surface;. -- in order to prevent the possibility of water entering the lever box and spool control kit, do not use high pressure wash down directly on the valve.
